The purpose of this experiment was to see if the percentages of colors in an M&M bag, given by the M&M Mars company, were correct. For this experiment, plain and peanut M&M's were separated by color, counted and the data was recorded. This was done in five bags of both types of M&M's. Then the percentage of each color was calculated for each bag, and those percentages were averaged together to find the overall percentage for each color.
At completion of this experiment, it was found that in the plain M&M bags, brown was the dominant color. Brown had 32%, red had 21%, yellow had 25%, blue had 9%, green had 8%, and orange had 5%, which is a little lower than the ten (10) percent it was supposed to have. In the peanut M&M bags, blue was dominant with 29%. It should have had 20%, just like the red, but the red had 11%, brown had 19%, yellow had 13%, but should have had closer to 20%.Green and orange should have had 10%, but they had 15% and 14%, a little higher than expected. The hypothesis was partially accepted because some percentages were too high or too low.
